PRIMING- DEVCE.

Application filed December 17, 1923,

To all whom t may concern.'

Be it known that i, @traumas S. Runs. a citizen of the United States, residing at Fort Myers, in the county of Lee and State of Florida, have invented certain new and useful Improvements in Priining Devices, of which the following is a specification, reference being had to the accompanying draw ings.

rihis invention relates to priming devices and has for an important object thereof the provision of a simple, readily manipulated control device whereby an internal concbustion engine may be primed in starting and supplied with auxiliary air during operation.

A further object of the invention is to provide a device of this character having a single control element which by its operation controls the amount of air delivered to the engine either during the priming operation or during` the supply of auxiliary air to the engine.

still further object of the invention is to provide in a device of this character a casing adapted to contain fuel for supplys ing the engine during starting thereof, this casing being` so constructed that a single control element associated. therewith will direct air admitted to the casing either into Contact with this fuel for mixture with the fumes thereof or directly to the outlet of the casing so that it is unmixed with these fumes.

These and other objects attain by the construction shown in the accompanying drawings, wherein for the purpose of illustration is shown a preferred embodiment of my invention and wherein Figure 1 is a side elevation partially diagrammatic, showing a device constructed in accordance with my invention attached to the intake manifold of an engine:

Figure Q is a vertical sectional view through a preferred form of priming cup;

Figure 3 is a similar section taken at an angle to the first section, showing the device in the priming position; j

Figure et is a plan view of the priming cup, parts being broken away;

Figure 5 is a plan view of the cup with the valve disk removed;

Figure 6 is a vertical sectional View through a slightly modified form of the invention;

Figure 7 is a similar view showing the Serial No. 681,192.

form disclosed in Figure 6 in the position in which air is admitted to the casing;

Figure 8 is a plan view of a further moditied form;

Figure 9 is a plan view with the disk removed;

Figure 10 is a section on the line lO-lt) of Figure 8; and

Figures 11 and 12 are sections on the line X-X of Figure 9, the disk being shown in closed and pure air feeding positions.

Referring now more particularly to the drawings, the numeral 10 indicates a control casing preferably provided with an attaching element 11 whereby it may be mounted at a point convenient to the ope i tor of the engine as, for example, upon the steering` post 12 of the vehicle and the casing maintained in a vertical position. This casing is provided in its lower end with an outlet 13 communicating through a conduit 1-1- with the intake manifold 15 of the engine at a point common to the cylinders 16 thereof.

The casing 10 consists essentially of a cupshaped bottom portion or body 17 and a cap section 18. In Figure 2 the body portion is shown as having projecting upwardly from the bore 19 of the outlet 1S thereof a cylindrical baffle member 20, which baflie member extends adjacent to but terminates short of the under surface of the cap member 18. The cap member 18 is shown as provided with a depending cylindrical baflie wall 21. ilhile this wall is preferably carried by the cap it may be simply positioned thereby, as indicated in Figure 2, in which event it will extend entirely to the bottom of the casing and be provided adjacent its bottom with a plurality of openings 22 for the passage of air. Anv desired means may be employed for positioning the baffle wall 21. In the present instance the under surface of the cap is shown as provided with a depending hub portion 23 aocomplisl'iing this result.

The upper surface of the cap has formed therein a pair of openings 24 and 25. the first communicating with the interior of the casing 10 interiorly of the batlie wall 21, while the second communicates with the interior of the casing exteriorly of the baile wall 21. The upper surface 26 of the cap or closure 18 in this form of the device is preferably ground and provided centrally with an upstanding stud 27 forming a pivot upon which is mounted a rotatable valve disk 28 the under surface of which is ground fill for coactionV with the ground tace 26. rlhis valve disk has formed therein a series of openings 29 selectively alignable with the opening 24 of the cap 18' and' With a single opening 30 alignable with the opening 25. This single opening is so arranged With respect to the series ot openings 29 that when the openings and 30 are aligned all of theYA series of openings 29 are out. ot alignment With? the opening 2st and when Yany of this series is aligned; With the opening 2li the opening 8O is out ot alignment with the opening 25.'- Tlic upper surtace oic tliexdisk about the opening is preferably provider with a tunnel'l, the purpose ot which Will presently appear.

The' periphery ofthe disk is provided with a plurality of notchesV 32' selectively engageable with a spring' latch33, this latch yielding to'permit rotation of the disk-Which rotation may' be accomplished either by actually engaging` the disk n'ith the hand or by employing' the funnel 31 as a handle.

vEach, ofk the notches is provided with suit-A able indicia to vindicate thev results of vpositioning of the diskso that this notch is engagedrby the spring latch 33. For example.,Y

one ofthe v notches is indicated hy O' and indicates, when this notch is engaged by thel latch 33, no= air Whatever is passing through the casing or through thc conduit 14a: Adjacent this notch are a pair of notches closely spaced and indicated as P1 and P2.

`When the lat-ch is engaged with the first ot these notches the priming opening'BO is aligned with the openingv25. lVhen engaged With the4 second of these notches thev openingaBO is out ot alignment with the opening25and no air is passing through theconduit'lll. The remaining notches correspond' in number and' arrangement to the series of openings 29 andf are numberedac` cordingly so thateach notch indicates the amount ot air'admitted to the opening 24.

In the operation of the device and in start;- ingf 'the engine,. the dislr is preferably arrangedso that the notch P1 is engaged by theflatch' 33 andv a small quantity ot prim'- ing Huid. such as gasoline. is poured into the: casingvthrough the tunnel 31.. 'The engine is thenoperated to start the saine with thev resulttliat air is'dravvn into thel inanitold through the opening 30 and must pass through the' gasoline Within the casing tov reach the' outlet lfiand coi'idu-.it 14. During its passage' it is mixed with the fuelv so th at a very rich mixture is admitted tothe 'inani- Jfoldk promoting starting of the engine. After the engine hasstarted the disl is ro# tatedto bring the notch P2 into alignment Withthe latch in Which position all open- ;ings are closed'and lin thisposition the en- ,gine 'is operated until it has heated and is runninglin a normal manner. f After the enygine has heated the disk is rotated in the saine direction to bring one or the other of the openings 29 into alignment with thev opening 24 with the result that air is admitted to the casing Without contact With the fuel contained Within the casing, passing'directly through the tubular baiile 2O to the outlet 18 and conduit 14. form of the invention it Will beunderstood that the secondary air or auxiliary air, as it might he termed, has 'no mixture With the priming fluid after the engine'has actually started. It desired the space between the'I inner tube or bafiie 20 and the outer Wall oi" the casing may be tilled with ifibious mate rial such as cotton generally indicated at' C Y inv Figure 3. Thisbrous material tends-toretard the air and to cause the same to more' in a tortous path so that it is more thoroughly saturated With the priining'luid hey' tore leavingl the casing. Y

1n the torni shown in Figures 6 andf, the cap 18 has a threaded engagement through a flange 34' with the casing 17. VThe conduit 2() is ot such length that When the cap" isin its lowerniostposition it contacts against the upper end of the conduit 2O to close the sainel and prevent the passage oit air therethrough:VY

Throughthe cap`18 an opening Srisformed lith this exteriorly oitl the battle Wall 21,the upper sur;

tace of the cap being provided-With the tunnel 31. i Y y v. lith this 'lorin of device the fuelvis admitted through the funnel andl the cap ro tated until the under suriace of the eap-V is spaced trom the upper end of the tube 2Ol av distanceto permit the desired amount of air. The entering air passes tl'iroughLv the priming fluid and out through the conduit 20 and A,

conduit 14e to the manifold. After the ein gine has started the amount of air admitted may he' reduced so that a small amount' oil highly charged air is admitted to the cylinders duringthat period in Whichthe engine is Warn'iingup. After the engine hashecoine warm the small amount of primingfluid admitted to the casing will become exhausted and at this time the admission of uncharged air canv be advantageously Aresorted. to With the result that air can be admitted; througl-i the opening 35and pass through the conduit 2O to the conduit 14. to assist in the torina@` tion o'li the' charge Ytor the engine. Vthisv air being unaccompanied by any prim-ingfluid.. The amount oi" air so admitted may ber'so very closely vregulated by Ameans ot'the threaded Aengagement Vot the cap 118 andeasing'l. In this form of the inventioircotton or other librous inateiialmay be emV openings 36. The baiiie wall 21 is omitted forming a relatively large chamber' 3T which is filled with cotton or similar fibrous material. rthe head of the cylinder is constructed after the manner of constructing lthe head in the form shown in Figures 2 to The upper end of the battle a being enlarged, as at 38, so that the engaged pertion of the head is of suiiicient size to permit a ready formation of the opening 24 therein. The operation of this form of my device is exactly the same as that of the form originally described. The upper disk being rotated to successively bring the notches P1 and P2 into engagement with the latch to start and for a running position of the engine until the engine is heated, after which a selection of the openings 29 is effected.

It will be seen from the foregoing that a device constructed in accordance with my invention provides means for admitting a priming charge to the cylinders and for subsequently admitting a controllable amount of uncharged air to modify the charge received by the engine from the carburetor ett). It will furthermore he seen that structurally this device is capable of a considerable range of change and modification without in any manner departing from the spirit of my invention and I accordingly do not limit myself to such specific structure as hereinbefore set forth except as hereinafter claimed.
